No, hardware RAID wants drives with TLER installed. TLER is meant to only be used with RAID edition drive, but you can patch it into the retail versions. One of my WD10EADS drives has the occasional locking issue, but to be honest it's no big deal at all. If I was going RAID I would apply TLER to it anyway and the problem would 99-100% certain go away. I would much rather have a slight stutter in performance than have a drive lose all my data a few months down the line as I would get with a Seagate (and possibly a Samsung as well).
